SPECIFICATION forming part of Letters "Patent No. 692,709, dated-February 4, 1902. Applicant inea rune 17. 1901. serial ne. 64,936. (No model.)

T0 @ZZ whom, it may concern'j Be it known that I, GEORGE W. PRICE, a citizen of the United States', residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Vrenches, of which the following is a specification.

Myinvention relates to a wrench which may be used either on a pipe or on anut; and the object is to provide a wrench which is easily adjusted to t different-sized pipes or nuts and which has a great holding power. I accomplish this object by the wrench described herein and illustrated in the accompanying drawings, in which-'- 3 Figure l is a side view of my wrench. Fig. 2 is a section on the line 220 Fig. 1, the adj listing-screw being shownv'inV elevation.

In the drawings, A is the m'ain'loar, having the integral head or fixed jaw A' and being pivoted to the handle B. Slidingly mounted on the main bar intermediate the fixed jaw and the main handle is the sliding jaw D, having therein a recess D' for the reception of the head of adjusting-screw E, which head is slightly oval, so that the head may have a slight working motion i-n the-recess. The top and bottom of the opening inthe sliding jaw, through which the main bar passes,- is slightly curved in opposite directions, as shown in dotted linesin Fig. 1, so that the sliding jaw may have a slight rocking motionthereon'. The adjusting-screw passes in,` threaded contact through the cylinder F, revolublymounted in arm B of the handle. The opening through the arm of the handle for the passage of the adf j usting-screw is so formed that th e screw may have a slight oscillating movement therein. (Shown in dotted lines in Fig. '1.) A thumbpiece G on the end of the adjusting-screw provides means to conveniently 'rotate the same to adjust the sliding jaw. The fixed and sliding jaws may be provided with removable serrated jaw-facing plates H, which are provided n the baci; sides thereofwith dovetail projections H', which fit into corresponding dovetail grooves in the ljaws and are secured therein by screwsI oi' otherwise aftixed thereto. When the wrench is to be used as a nutwrench', the face-plate may be removed.

It will be observed that a medium-sized wrench may be used.. as a pipe-wrench on Y many sizes of pipe or nuts, and owing to the power imparted to the sliding jaw by reason of the leverage in having the handle pivoted to the main bar the more force that is put on the handle the tighter the jaws will be caused to grip the pipe, and that the opposite move-` ment of the handle will cause the jaws to promptly loose their hold on the pipe or the nut.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-f- 1. A wrench comprising a main bar having a fixed jawvand pivoted to a handle; a sliding jaw on said main bar, having a recess therein for the reception of the head of an Y adj usting-screw the handle having a projecting arm; a cylinder having a transverse screwthreaded hole extending therethrough revolubly mounted in said`arm; an adjusting-screw passing inthreaded contact through said cylinder and having a head adapted to fit in the recess in the sliding jaw.

2. A wrench having a handle pivoted to the main bar carryinga fixed jaw, and the handle provided with a projecting arm; a cylinder in said arm, having a transverse internally-y threaded holeextending therethrough an adn j listing-screw in said cylinder; a sliding jaw on the main bar, and being connected with and adapted to be moved by the adjustingscrew.

' 8. -The herein-described wrench, comprising the main bar A, having fixed jaw A integral therewith; the handle B having proj ecting arm B', the said handlgleing pivotedl to the main bar cylinder F in sa' arm, having an internally-threaded hole ext nding transversely therethrough; an adjusting-screw E in said cylinder; and the slidingy jaw D on the main bar; the said jaw being operatively connected with the adjustingscrew, substantially as herein shown and described. 1

In witness that I claim the foregoing I have hereunto subscribed my name this 10th day of June, 1901.

. GEO. W. PRICE.
